Could you please explain the reason for the above error logs? The current cluster has issues and keeps switching between down and up states.

Are the PD nodes functioning normally?

| username: 月明星稀 | Original post link

It’s not normal, it’s also down.

Based on this log information, it is only known that the Grpc request from TiKV to PD timed out, and it is continuously retrying the request.

Please provide more log information about PD, as well as cluster information and other details, otherwise, further analysis is not possible.

The kv error is likely caused by the PD being down. What error is the PD reporting? If you want a quick fix, you can directly scale out a PD and remove the down PD.

I feel like I should report a bug to TiDB.

Check the status of all nodes in the cluster.

First, check the PD on the cloud. Once the PD is normal, then check if this side is normal.
